[jira] [Created] (PDFBOX-4771) JPEG image with transparency can't be extracted

Tilman Hausherr created PDFBOX-4771:
---------------------------------------

             Summary: JPEG image with transparency can't be extracted
                 Key: PDFBOX-4771
                 URL: https://issues.apache.org/jira/browse/PDFBOX-4771
             Project: PDFBox
          Issue Type: Bug
          Components: Utilities
    Affects Versions: 2.0.18
            Reporter: Tilman Hausherr
             Fix For: 2.0.19, 3.0.0 PDFBox


See TIKA-3040, "javax.imageio.IIOException: Bogus input colorspace" when trying to save /DCTDecode encoded image that has a mask, because JPEG images can't have alpha.

I need to think about this a bit, but we'll probably have to save it as a PNG image.
